  • Method of determining a maximum transmission unit value of a network path using transport layer feedback
    Patent number: 7738495
    Abstract: A network element implementing a method for determining an optimal maximum transmission unit (MTU) value on a path between two nodes in a network is described. A sending node interested in learning the optimal MTU path value allows fragmentation of datagrams sent on the path, selects an initial MTU, and sends one or more data packets to a receiving node. Upon receiving the data the receiver determines if fragmentation occurred. If no fragmentation occurred then the MTU path selected is the optimal MTU for the given path between the nodes. If fragmentation did occur then the sender is notified that the selected MTU was not the optimal MTU for the path. Either the receiver proposes a new MTU for the path, or the sender selects a new, smaller MTU. The process repeats until the receiver detects no fragmentation.
